The benifit is there is zero boost pressure being put on the WG diaphram, when energized, causeing quicker spoolup.

Both the stock, or aftermarket ECU can control this solenoid. It has the same resistance as the stock solenoid so there is no risk to damage of the drivers in the ECU. If you set it up like an interuption type on your stock ECU, you will have boost spiking issues. Not much just a little. If you use this on a reflashed tuned ECU, the boost parameters are adjusted so high(to accomodate the stock boost solenoid) that it will have really bad boost spiking problems.

"It will build boost like an ACVR" means that the way our solenoid works is like an AVCR. It blocks the boost signal going to the WG, which means zero pressure on the WG which in turn builds boost quicker. The quicker response time of this type of solenoid will build boost quicker in lower gears like the AVCR does. Since it is just a solenoid, there is no programming for different gears.

The stock ECU is very good at controlling boost if given the right tool, our EBCS. The stock solenoid is setup to bleed boost to control it. This in self isn't very good because you have to rely on a solenoid that is large enough to FLOW the boost from the system. With ours you are blocking the boost from getting to the WG, there is no need to use an MBC. This was a good trick to use in line with an AVCR. You could run your MBC at 15PSI and use the AVRR to get to 20PSI. The only reason for this is to lower the needed duty cycle for the desired boost. I have found around 40% less Dutycycle need to control the same boost needed on an AVCR.
